I have. She's got 6, by the way. Maybe check that discography?
4 of them are complete shite and two that have branched out a bit from DisPop aren't much cop. Few decent songs. That's it.
Actually there are lots of different measures of popularity. Which one do you think they should use? Album sales, singles chart positions, Spotify listens, TikTok followers, ticket sales? Historic ticket sales or last couple of years? You’ll get different measures on all of them.
Where were promises made about Glasto being ‘the best?’ How do you definite ‘the best?’ What makes this set of headliners not ‘the best?’ Which more “popular” acts should they have booked instead? What kind of ‘spectacle’ would they provide? How important is ‘spectacle’ in terms of booking a headliner? Would they be a balanced set of headliners in terms of crowd appeal, ‘popularity’ and ‘spectacle?’
Even before you start on other questions (If the festival decides to bin one of the 3 headliners is there a guarantee they’ll be able to book them again? How much do your alternate set of headliners cost and how does that affect the budget elsewhere?) a lot of it is subjective, and you’re trying to apply objective measure to subjective things.
AM had two albums in 2007 so I'm not sure if the comparison is as strong there. Maybe it would've been if in 2005, The Killers had been bumped up to replace Kylie as they were apparently offered and turned down as they themselves said it was too soon and wanted to stay as sub-heads.
Think there's good info, but looking at (the other place), Underworld are now Saturday park headliners which makes The Jaxx more likely for Friday or Sunday instead.
